Single-unit double-track blind system with fly net and blind

Abstract

A single-unit double-track blind system comprises two tracks, one for a fly net (28) and the other for a blind (27), combined in a single unit. The tracks may be oriented so that one of the fly net (28) and the blind (27) opens horizontally and the other opens vertically. The unit comprises four corner pieces (1A, 1B, 3A, 3B) connected by four linear pieces (10A, 10B, 13, 18). The linear pieces may have a stepped profile, whereby inner portions of the linear pieces carrying one of the tracks can fit inside a window or door opening, while outer portions of the linear pieces carrying the other of the tracks can overlap the edge of the opening and rest against a wall (40) or frame adjacent to it. The overlap hides any gap between the unit and inside of the opening, thereby reducing the precision required when measuring the opening for installation of the unit.
